it goes surggey,!!!

i've got some atmo BOV, and a GFB manual boost controller and a HKS Pod.

any ideas? i aint got much left to replace and rather spend it on BLING BLING then crap parts that dont fix it!!!

atm its running 13PSI

600 x 400 x 75 FMIC...

S/S 3" 1/2 inch turbo back WITH 7 " n 1/2 turbo box...

Forged pistons/rings/pins/shells/graphite gaskets etc...

cleaned/flowed/ported head with new stemseals/core plugs etc...

Stock ECU...

New Platium NGK Plugs 'yes pre gapped as per manual'...

GFB Manul boost controller...

HKS Replica SSQ BOV...

HKS Pod Filter...

Twin Plate Clutch...

HSD Coilovers

Yep thats it...

haha thanks lighty01... well could be, its hanging there LOL... maybe i should invest in a electric one?!

um i recently topped my batterie up with some distilled water, and put my stock BOV back on.

Doesnt have as much power... cause the stock BOv its leaking of the extra boost?

and also i got no 'PSTTT' noise going through the pod no more!? i use to ages ago....

any reasons why its not? i heard its called blowback... and its not good... correct?

well my problem i found that an intercooler pipe was blowen off... and leaking off boost... causing my other problem, along with a el cheapo BOV adaptor isn't 100% flat =/ i think thats it... not sure?!

else i might look at AFM or CAS timing...

if your loosing boost, check all your vacuum lines, cooler pipes and the BOV, if its a HKS replica its obviously cheap shit and quite possibly leaking boost.

get rid of the GFB boost controller and hook up your standard solenoid (if you have one) that should run 7psi on highboost and if it doesnt piss around and carry on then you know the valve is bollocksed (which wouldnt be hard do believe)

also, remember the standard ECU has a boost cut, if your running a squillion pounds on your standard tune the engine WILL stop it from boosting, mainly to protect the engine. ALSO! you have a standard AFR.

so your fuel/air ratios are not tuned and the more boost you run with a standard setting the more its not going to like it.

basically it could be anything. just have a look at all that.

but the factory BOV leaks of excess boost though!

my AFR are 11:## @ 13PSI, and yea it was at 1 BAR but i lowered it on the dyno lol to get higher HP.

and yes its a series 2 turbo

i am pretty sure thats save enough @ 11 ish air / fuel ratio!!

wether your turbo is safe at 13psi and 11.0:1 A:F ratio has nothing to do with the stock ECU going spastic due to AIR FLOW at that sort of boost at those revs.

just have a look at the thread titled "quiet screamer pipe".

the started "RB2530" has a few things to say about stock ecu and AFM cut etc.

Page 3 I think..

      Rusty roof repair

      Nah that is not actually a lot. Just painting my GTR frontend and the little bits to make sideskirts/nismo flare pieces work correctly/fit on the sedan/mount up correctly came to about $7000. Is it a lot? Sure. None of this is economical. Economy would be shelling the car and buying a 2010 Corolla to commute in. The perspective of all of this is different.

      I don't see any issues here. I've been saying all along this is a big job, the price reflects that.  When the car comes back perfect I'm sure it will feel like money well spent.

      Remember, take original quote. Double it. Then add a bit more. It's how any project goes.

      Rusty roof repair

      By PranK · Posted

      So, I started this repair and got as far as "fixing" the holes with some fibreglass. God all those years working on boats came back quickly. I decided I'd reach out to some rust guys just to see what they would say about it. I came across a guy about 40 mins away and went to see him. He said the windscreen needs to come out, that there might be some more bits around the windscreen and he'd quote them at the time. But his quote was $300 to remove and replace windscreen and $3k for the damage he can see. He said he could respray the roof for $1200 and the bonnet for another $800 (somebody has previously rattle canned it, its horrendous). This is $5300 + any small additional bits. It's a lot, I get that and the name of one of my fave youtube channels 'Not Economically Viable' comes to mind.  I'm not being financially rational, but I've taken him up on the quote. He's opening a new shop in November with more room, so we're waiting for that. I'll leave the currently missing headliner out until then. I'm looking forward to it being fixed and having the paint looking nice again (lots of clear coat issues on the roof too). / flame suit on.
